macOS 10.12.5: pkg_add segfault installing python27

[Michael-John Turner <mj%mjturner.net@localhost>]

Hi,

I'm using pkgsrc HEAD on macOS 10.12.5 and after a recent update, 
installing my self-built package of python27 fails with a signal 11.
Oddly enough, even installing an old python27 package, which had installed 
fine several weeks ago, now fails with the same error.

===> Installing binary package of python27-2.7.13nb1
/bin/sh: line 1:  3027 Segmentation fault: 11  /usr/pkg/sbin/pkg_add -K /var/db/pkg /usr/obj/pkg/lang/python27/work/.packages/python27-2.7.13nb1.tbz
*** Error code 139

Stop.
bmake[2]: stopped in /usr/pkgsrc/current/lang/python27

The package is available here: 
http://dl.rsx11.net/misc/python27-2.7.13nb1.tbz

Full crash log:

Any ideas?

Cheers, MJ
